Most teams dont get the reviews right. But Pakistan seems to be the worst team in using the reviews (whether its bowling or batting)....
Pakistani players always ask for a review, when its a close call (which could have gone wither way). Aren't the players aware of the fact that without the use of snickometer and hotspot, any faint edge will probably will be a wasted review. Similarly for any lbw decision, if ball is clipping part of stumps, the umpires call will remain.
But our players keep on repeating same mistake again n again. DRS should only be used for howlers / plumb lbw (where the ball is probably going to hit middle stump), and other straight forward mistakes by umpire...
